T all whom 'it may concern.'

.Be it known that we,iFonnns'r Bnnnnn, O'r'ro 7. PMU, and RICHARD Ol Jisoriiiowsknresidinf; in Chicago, in the county oit (look and State of Illinois, have invented certain new and use-'ful Improvements in Fum ps, of which the 'following-is a specification. y

Our invention relates Ato 'Improvements in pumps, and more particularly to a-tluid operated pump which is simple. and compact in construction, durable, reliable,y efcient and. satisfactory tor use whereifer 'found applicable.

More especially our invention relates toa pumping apparatus andvsystem wherein, the Atiuidsuch as water or the like is pumped direct from the source ot supply such was a well, cistern, pond, etc., to thedischarge point or points without storage, the pumping being.;` automatically governed by the demand at the discharge point orpoints.

lt has among its i'urther objects` the production ot an apparatus that. willbe operative ywith a minimum of attention and care and without requiring the attention Ot one skilled in the handling, care and use of the same.

nother object ot our invention is to provide a fluid motor in combination with` a l'luirl-olierated pump, said `motor and pump being' operatively connected together so that the motor will transmita puinp-operating` lluid the-reto, and wherein the operations will automatica-ily cease when the pressure olE the motive iiuid for operating the pump balances the pressure ot the motor-operating fluid. Y

In the drawings, wherein we have illustrated a preferred embodimentot our invention. l indicates a well, cistern or the like, havingl water therein which is intended to be conducted to a house, barn or other desired points. A pump 2 is in direct communication with the liquid ot the well and has a discharge line 3 leading to one or more iaucets 4. A check valve 5 is preferably' placed at some suitable point in ythe line so as to prevent the return ol' Water to the substantially on trips Cil .termediate said compressor and tank.

pump, and an air chamber 6 is also arranged i size and shape and connected to said storage tank by an inlet pipe 9. One or more pressure coi'itrelling or reducing and check valves 10 preferably are arranged between said tank and meter, and there are one or more pressure indicating gages 11 so that the pressure at various points in the line may be ascertained.

n air compressor 12, driven by a gasoline engine 13, electric. motor or other source of power has a pipe 14 leading to said tank, there being a safety or blew off valve 15 in- A drain valve 16 is arranged adjacent the bottom of the tank for the purpose of exhausting air therefrom and removing any sediment from within the tank.

rlhe pump 2 (see Figs. 7 and 11) is fiuidoperated or controlled and comprises a casing 17 having top and bottom cover plates or walls 18 and 19 respectively so as to 'form a main chamber 20. the top cover 18 being` chambered to provide a casing having an auxiliary chamber 21 independent of said main chamber and other chambers and ducts hereinafter referred to.

A cover plate 22, having a central aperture 23, is detachably secured to said casing so as to close the auxiliary chamber 21, by means ot screws 24. or other suitable or equivalent means. The bottom 'wall member 19 is apertured in direct communication with the liquid in the well. and to provide an intake 25, an intake valve 26 slidably movable thereat being arranged to control the admission et liquid through said intake into said main chamber 20. An air inlet port 27 is provided at the top cover 18 and communicates with the main air chamber 20. An inlet valve 28 is positioned at said inlet port so as to control the passage of inid through the port 4and admission ot air into said chamber.

Between said inlet valve and cover plate 18 is a spring 29 resiliently urging the closure of` said air inlet opening. Depending from the cover plate 18 and extending into the chamber 2O is a sleeve 29 having ports 30 through the wall thereof adjacent the upper end, said ports lcommunicating with afdischarge or exhaust outlet 31. An air discharge pipe 32 communicates with said exhaust outlet 31 at one end, and has its other end 33 above the level of the water in the well, as shown in Fig. 1. A valve 34 is slidably arranged within the sleeve 29 to control the discharge of air through the exhaust outlet 31, said valve being annularly grooved as at 35 for rings or packing material to provide a seal between the valve and sleeve. At the upper face of the valve 34, there is formed an annular recess for receiving a packing ring of rubber or other suitable resilient, compressible material and adapted te bear against the lower end of the opening 31. The valve 34 is axially bored andA at the lower end receives a setserew 36 said setscrew being adjustable relative to said valve and having a bore or recess 41 therein, open only at one end of the screw. An arm 37 extends laterally therefrom and is adjustably connected to the valve stem push rod 28. whereby both the valves 28 and 34 may be moved in unison (see Fig. 7). A stem 38, having an enlarged collar 39, is slidable within the axial bore through the valve 34 and is prevented from accidental disengagement therefrom by means ot' said collar 39. The lower portion 40, of said stem arranged withinthe bore ot the valve 34, is adapted to abut against the.

screw 36 in the recess 41 just betere the limit of its downward movement. v

Ve have shown a spring 42 arranged between the screw 36 and the collar 39, the spring being slightly depressed during the downward movement of the stem so that when the end 40 engaging with the screw 36 at the bottom et the recess y41 moves the valve 34 towards its open position, the spring will immediately snap the parts to wide open position and maintain the same open until the collar 39 engages the end of the plunger, positively moving it to its closed position. At the upper end of the stem 38 is arranged a piston 43, which is slidable in said auxiliary chamber 21 and is Controlled by the fluid in the chamber at the inlet opening 23. a coiled spring 44 or the equivalent is positioned behind said piston so as to return said piston to its normal position, substantially as shown in Fig. 7, when the air pressure upon the opposite face of said piston has been released.

.A water discharge pipe or main 46 is ex tended through the cover 18, the lower or intake end of the main being at a slight distance above the intake valve 26, lbut not interfering with its freedom of movement. Communicating with the inlet 27 is the air pressure line 47. and leading to the auxiliary inlet 23 is the air pressure line 48, both said air lines communicating with the air motor 7. i

The operation of the pump is as follows: Assuming that the intake 25 is open, the chamber 2O having water there-in, then if air under pressure is admitted through the pipe 47 through the inlet 27 it will exert a force llO through the water main 4G, so that it may be discharged at the 'faucets 4. When the i water in the chamber 20 has been substantially emptied therefrom, air .under pressure is admitted from the air motor through the pipe 48 and into the auxiliary chamber 2l, moving the piston 43 against the spring tension 44 theI moveniienit ot the piston serving to actuate the valve 34 the pressure oit the spring 4:2 to open` vthe ports 8() and 3l to the chamber 20. lt will be seen that as the valves 28 and 34 are rigidly connected, when one oil them is opened, the other 'will be closed. Therefore, when the piston 48 opens the exhaustports 30 and 3l it will close the air passage through the air inlet port 27 whereby the air within the chamber may be exhausted through said exhaust port per-` mittingthe water in the well or cistern under atmospheric pressure to lift the intake valve 26 and iill the chaml'ier 20. Substantially expelling all the air throughy the exlia-ust.

Means, which will be hereinafter described, are provided to coifnn'iunicate with the pipe 48, whereby the air that is admitted through the pipe 48 has but a momentary Vpiston-driving effect, so that it will drive the piston 43- to open the exhaust valve which opens with a snap action, but as the air pressure in the line 48 is` suddenly terminated, the piston 43 willbe moved to its normal position by the spring 44, as; shown in Fig. 7, thus serving to close the exhaust ports. At the same time air from pipe 47 is again admitted forcing the water out through pipe 46, the action being repeated as described.

The motor 7 comprises a hollow casing or cylinder 50, with a lower or bottom. cover plate 5l, and a top cover pla-te 52, said top plate having a pair of chambers 53 and therein. The pipe 9 from the tank 8 leads to an inlet chamber 5G adjacent thefchamber 53 but not in direct communication therewith. The inner wall of the chamber 56 has a. pair of inlet ports 57, 57', there-in, -communicating with the valve chamber and. there are a pair ol' valves 58 and 58" controlling said ports 57 and 57" respectively, the valve 58V permitting lthetl'uid admitted into the inlet 5G to be passed through the valve chamber into the chamber 54I- while the valve 58 controls Ithe passage ot `air trom the inlet chamber 56 through the port 57 and into the upper end of the 'casing 50. The air admitted past the valve 58 into the chamber 54 will flow through a duct 59, as shown more clearly in Fig. 20, and thence. 'flow exteriorly of the casing 5() through a pipe 60, which, as shown in Fig. 22, leads directly into the lower end 'ot the hollow casing. A piston 60'* isl arranged within said casing or cylinder so as to be reeiprocatory therein, said piston having a piston rod (il movable relative to the piston .in one direction of movement (downwardly, as shown in Fig. 22), and con'iprisifng several telescopioal'ly connected sections so vthatthe piston might be termed.y a jfioating piston. The telescopic sections of the piston rod comprisel the part 6l, to which is detachably connected a rod-l portion 62 oft large diameter said portion 52 having an axial recess G3 in the upper end thereof, and into this recess 63 is arranged another section 64 of the piston rod, the part 64 telescoping into the recess 63. An enlarged head 65 is arranged on the lower end ot the section 64 ot the piston rod, whereby ythe expansion or separation ot the sections arev limited in one direction. of movement. A sleeve ($6 encircles the rod section 64, and bears against its upper end and a nut 57 is arranged at the opposite end ot the section 64, there being a spring 68 between the sleeve and nut, whereby the contraction ot the telescopic sections 62 and 64 of the piston rod are yieldab-ly resisted. A bushing` 69 is fixedly arranged on the enlarged piston rod section 62, and an oli'set pin 70 projects laterally therefrom. Surrounding' the bushing 69 and slida'ble relative thereto is a sleeve 71 having a longitudinal slot 72 therein, through which the pin 70 projects to `prevent any relative rotation of movement between the sleeve and the piston rod. A. pair ot discharge valves 7 3 and 74 are rigidly connect-edi together by a tube 75, said tube encircling the sleeve 7l. rlhe upper end of the sleeve 7l is reduced in diameter, as at 76, andhas a `pair ot annular shoulders or collars 77 and 78 axially spaced thereon, the upper collar 78 being preferably adjustable on the portion 76. Engageable with sai-d shoulders 77 and 78 are washers 79 and 80 slidaibfly arranged within the tubular part 75 and having a spring 8l between sai-d washers, whereby the sleeve 7l may be moved a slight distance, relative-ly to the tubular portion 7.", against-the pressure ot the spring 8l without straining any of the abutting parts.

Discharge ports 82 and 83 are arranged So as to lcommunicate with the chamber 53,y both of said discharge ports communicating' with the piston chamber, Aone of said ldischarge ports 82 arranged in the wall 52 betweenv the piston chamber and the chamber 58, and encircling the tube 7 5. and the other discharge port 88 arranged between the chambers and 54 'and coaxial with and encircling the tube 7F. 73 and 74 are arranged so as to overlie the inlet valves 58 and 58" so as to be engageable therewith when the discharge valves are moved. one ot said ports being open whenever the other is closed. Packing rings 55 The discharge valves l CII are arranged at the oppositely facing ends ol the valves 73 and 74 so as to bear against the openings 82 and 83 said packing rings being preferably ot rubber or other Suitable resilient or compressible material.

In the operation of the motor, air under pressure is admitted through the pipe 9 into the inlet chamber 56, and, assuming that the inlet valve 58 is open, as shown in Fig. 15, and the inlet valve 58 closed, then the air will pass through the port- 57 into the chamber 54 and downwardly through the ducts 59 and 60 to the underside of the piston, driving the piston upwardly at first, relatively to the piston rod, and then with the rod, so that the driven luid on the upper' side of the piston is discharged through the discharge port 82 into the chamber 53 and outwardly through the pipe 47, communicating with the pump inlet. At substantially the end ot stroke the valve 58 is closed and valve 58 opened. For the opposite stroke of the piston, the air coming through the pipe 9 and into the chamber 56 will be admitted through the port 57 past the valve 58', the valve 58 being closed, and drive the piston downwardly in the cylinder, relatively to the piston rod at iirst and then togcther with said piston rod so that the air on the lower side of the piston is driven upwardly in the pipe 60 and the duct 59 into the chamber 54, where it passes through the discharge port 83 into the chamber 53 and passes downwardly in the pipe 47 to the pump air inlet.

In order to operate the discharge valves 73 and 74 quickly, or with a snap action so as to prevent a wire-drawing action at said valves, there are a pair of trips 85 and 86 positioned in the path of movement of the pin 70, the trips 85 and 86 being spaced apart axially of the piston rod and ixedly held in place by a rod 89 secured to the wall 52. .Springs 88 are arranged at said trips to yieldably resist the movement of the pin 7() and the piston rod, as said pin and piston rod are driven by the piston. A lug 87 is arranged on the sleeve 71 laterally thereof and ot a greater axial length than the distance apart of said trips so as to be engageable with said trips alternately to normally hold the sleeve against movement relative thereto. A screw 84 is arranged upon the trip support 89 and is engageable with the lug 87 to prevent the rotation ot the sleeve 71 but permit said sleeve to be moved axially.

Upon the upward movement of the piston, the piston rod sections are telescopically contracted in length against the tension of the spring 68, and with the sleeve 71 normally held fixed by the trip 86, the pin is moved by the rod 62 until it engages against the trip 86 at substantially the end ot its travel, the trip yieldably retarding thek movement ot the piston rod, but finally being released from its engagement with the lug by the pin 7 O, whereby the spring throws the sleeve 71 forwardly in the direction ot movement ot' the piston rod to simultaneously close the valve 74 and open the valve lllhen the lug is moved upwardly the upper trip trees itself of said lug and the lower trip moves into engagement therewith to yieldably resist the downward movement ot the sleeve and piston rod.

Upon the return or downward stroke the trip 85 is released in the same manner as just described in connection with the upstrolre, snapping the `sleeve 71 downwardly to snap the upper valve 73 to close the port and simultaneously open the port 82. It will be noted that the valves 73 and 74 are engageable with and operate the inlet valves 58 and 58', as shown in Fig. 15, and that springs 55 are arranged to actuate the valves 58 andl 58 to close the inlet ports, when the valves 73 and 74 are released therefrom.

At the lower end of the cylinder is a pipe 90, and into said pipe 90 is adapted to slide an auxiliary stem 91, closed at its lower end and connected to the under side of the piston, as shown in Fig. 2, there being play, or clearance, between saidtubular stem and the pipe 91 and 90 respectively, the stem 91 also serving to slidably receive the piston rod section 61, as shown in Fig. 22.

A check valve 92 is positioned at the lower end of the pipe 90, and is engageable with the stem 91 at the lower limit of travel of said stem, said check valve controlling a valvechamber 93 (see Fig. 3) communicating with the pipe 48, which, as has been previously described, leads to the auxiliary piston chamber 21 of the pump. Depending from thc valve 92 in the valve chamber 93 is a stem 94 having a vent 95 therein comn'ninicating with a vent 96, at the bottom of the chamber. In order to adjustably control the size of the vent 96, which is in communication with the valve chamber 93 when the check valve 92 is in the position shown in Fig. 3, a pair of setscrews 97 and 98 are adjustably arranged to intersect the bore of' said vent. mien the valve 92 is opened to permit passage between the pipe 90 and the pipe 48, the vent 96 is shut oft' trom the valve chamber. A spring 99 is arranged in the valve chamber 93 to automatically return the check valve 92 to its normal position after each operation thereof.

Assuming that there is air in the cylinder, on the lower side of thek piston 60, then when the piston is driven downwardly, the stem 91 secured thereto will at its limit of downward travel, engage the valve 92, so that a portion of the air before the piston will be driven into said valve chamber 93 and through the pipe 48, the major portion of the. air being driven up'w ardly.` through 1' theu pipe (Oi l Y pipe#lSIopc-rateswto vmore they `piston all,
